    •  DETAILED DESCRIPTION OF THE INVENTION
  • FIG. 1 is a schematic diagram of a hardware configuration of a system for managing a data transfer channel between communication devices (hereinafter, “the system”) in accordance with a preferred embodiment. The system typically includes a plurality of communication devices, such as a work computer 5, and a plurality of communication devices 4 (only two shown) connected to the work computer 5 via the Internet 3. The work computer 5 may include a communication interface 1, a managing interface 2 connected with the communication interface 1. A data transfer can be performed from one of above-mentioned communication devices such as the work computer 5, to another of above-mentioned communication devices such as the communication devices 4 through the data transfer channel. Both the work computer 5 and the communication devices 4 are configured (i.e., structured and arranged) for transmitting data carried by the data transfer channel, and the data transfer can be performed specifically between the communication interface 1 and the communication devices 4 through the data transfer channel. Both the work computer 5 and the communication devices 4 can be client computers, personal digital assistants (PDAs), or the like.
  • The communication interface 1 includes a plurality of data communicating tools 10 such as, Microsoft Network Messenger (shown with MSN.exe), Microsoft Internet Explorer (shown with explorer.exe), and Lotus Notes (shown with Notes.exe), for transmitting/receiving data carried by the data transfer channel between the data communicating tools 10 and the communication devices 4. The managing interface 2 includes a storage device 22 configured for storing security definitions predefined by a person, and a data manager 20 connected with the storage device 22, the communication interface 1 and the communication devices 4. The data manager 20 is configured for managing the data transfer channel between the communication interface 1 and the communication devices 4 by corresponding to the predefined security definitions. The security definitions are used for specifying sensitive/confidential data that is not permitted to be transferred between the communication interface 1 and the communication devices 4.
  • FIG. 2 is a schematic diagram of main function sub-modules of the data manager 20. The data manager 20 typically includes a monitoring module 200, an analyzing module 202, an intercepting module 204, a data processing module 206, and a data controlling module 208.
  • The monitoring module 200 is configured for monitoring the data transfer channel between the communication interface 1 and the communication devices 4 for a data transfer. It is generally known that a data transfer contained a destination address is performed when the work computer 5 is communicating with a communication device 4. The address of the data communicating tool 10 is the destination address if the data transfer is from the communication device 4 to the data communicating tool 10 through the data transfer channel. Otherwise, the address of the communication device 4 is the destination address if the data transfer is from the data communicating tool 10 to the communication device 4 through the data transfer channel.
  • The analyzing module 202 is configured for waiting for the data transfer by communicating with the monitoring module 200, and for detecting whether reassembled data include sensitive/confidential data corresponding to the predefined security definitions that specifies sensitive/confidential data not permitted to be transferred.
  • The intercepting module 204 is configured for intercepting data packets of the data transfer channel monitored by the monitoring module 200, and for retrieving the predefined security definitions from the storage device 22.
  • The data processing module 206 is configured for reassembling intercepted data packets into the reassembled data, and for formatting the reassembled data into the intercepted data packets if the reassembled data do not include sensitive/confidential data.
  • The data controlling module 208 is configured for releasing the intercepted data packets such that the monitored data transfer channel connection is allowed to transfer the intercepted data packets to the communication device 4 or the data communicating tool 10 according to destination address, if the reassembled data do not include sensitive/confidential data. The data controlling module 208 is further configured for preventing detected data from transferring through the monitored data transfer channel to the communication device 4 or the data communicating tool 10, if the reassembled data include sensitive/confidential data.
  • FIG. 3 is a flowchart of a method for managing a data transfer channel between communication devices by implementing the system as described above. In step S20, The monitoring module 200 monitors the data transfer channel between the communication interface 1 and the communication devices 4 for a data transfer.
  • In step S22, the analyzing module 202 waits for the data transfer by communicating with the monitoring module 200.
  • If the data transfer is not detected by the monitoring module 200, the procedure returns to step S20 as described above. Otherwise, if the data transfer is detected, in step S24, the intercepting module 204 intercepts data packets of the monitored data transfer channel, and the data processing module 206 reassembles data packets intercepted into reassembled data.
  • In step S26, the intercepting module 204 retrieves the security definitions from the storage device 22. In step S28, the analyzing module 202 detects whether the reassembled data include sensitive/confidential data corresponding to the predefined security definitions that specifies sensitive/confidential data not permitted to be transferred.
  • If the reassembled data do not include sensitive/confidential data, in step S30, the data processing module 206 formats the reassembled data into the intercepted data packets, and the data controlling module 208 releases the intercepted data packets such that the monitored data transfer channel connection is allowed to transfer the intercepted data packets to the communication device 4 or the data communicating tool 10 according to destination address.
  • Otherwise, if the reassembled data include sensitive/confidential data, in step S32, the data controlling module 208 prevents detected data from transferring through the monitored data transfer channel to the communication device 4 or the data communicating tool 10.
  • It should be emphasized that the above-described embodiments of the preferred embodiments, particularly, any “preferred” embodiments, are merely possible examples of implementations, merely set forth for a clear understanding of the principles of the invention. Many variations and modifications may be made to the above-described preferred embodiment(s) without departing substantially from the spirit and principles of the invention. All such modifications and variations are intended to be included herein within the scope of this disclosure and the above-described preferred embodiment(s) and protected by the following claims.
